Geopak Graphical Criteria
Shoulders
GGC Shoulders Summary
GGC shoulder Criteria is designed to identify the paved shoulders
(width) in a GGC plan graphics file. The user can then configure how to handle
the total usable shoulder width (paved shoulder + turf shoulder). Since the
paved shoulder limits are stored as graphics, its width can either be variable,
fixed or in combination of for the entire project. Both outside and inside shoulders
are accommodated with GGC. A minimum of one set of shoulder definition is recommended
in case a plan graphic paved shoulder line is not encountered in the Criteria
input file. This should offer more flexibility to Critieria users and eliminate
the need for multiple sets of shoulder definitions for projects with multiple
paved shoulder designs. Also a more accurate slope stake limits for guardrail
flare sections can be represented.
GGC Usage
CRITERIA FILE: SHLD01.CRI
DEFINE "GEOPAK GRAPHICAL CRITERIA FILE" (in Criteria input file)
GGC DGN: [TIP#]_rdy_ggc.dgn
GCC ELEMENT: copied from the DSN file using D&C Manager and adhoc attributes
attached.
- Level Name- Prop Paved Shoulder
GCC ADHOC ATTRIBUTES
- ggc_Shoulder Case
- ggc_Turf Shoulder Width (Applies to Configure Shoulder
Case #2 Only)
GGC D&C Manager

Configuration Shoulder Case 1 determines the total usuable
shoulder wdith from the Criteria input file. If the paved shoulder width is
greater than the shoulder width statement, then the total usuable width is the
same as the paved shoulder width.

Configuration Shoulder Case 2 determines the total usable
shoulder width by adding a fixed turf shoulder width behind the paved shoulder
line. Users can key-in a fixed turf shoulder width when presented with option
through D&C Manager. Case 2 is the only line item under the GGC paved shoulder
D&C folder that will open a dialog box for user's input.


Configuration Shoulder Case 3 determines the total usable
shoulder width by locating the shoulder line as a DGN Element defined in the
Criteria input file. This is an existing feature of Criteria and GGC was modified
to integrate it to its workflow.

GGC Adhoc Attributes Definition
| Name |
Value |
Description |
| ggc_Shoulder Case |
1 |
Total usable shoulder width from Criteria input file. This value is locked. |
| |
2 |
Total usable shoulder width is derived from adding a fix turf shoulder
width behind the paved shoulder line. This value is locked. |
| |
3 |
Total usable shoulder width is derived from locating a plan graphics defined
DGN Element in the Criteria input file. This value is locked. |
| ggc_Turf Shoulder Width |
0 (default) |
Only used when ggc_Shoulder Case value is 2. Key-in a desired
fixed turf shoulder width behind the paved shoulder line. |
GGC DEMO
Step 1.
Copy the paved shoulder line into the GGC DGN file by selecting one of the configure
shoulder case number in D&C Manager. Use the "dl=0,0" command
or one of the SuppAtta tools to copy the paved shoulder line from the DSN file
into the GGC file at the same location.


Step 2.
After processing the Criteria input file, the paved shoulder and total usable
shoulder widths are drawn by GGC.
Step 3.
Lastly, when generating slope stakes (limits of construction), guardrail
flares should shift accordingly.
